Dual monitors one touch screen the other a display

Hi,

This is something I’ve always wondered about. I have a dual screen setup one is touch screen and the other is not. On Ubuntu the touch screen works seamlessly. However in Ubuntu Mate I have to do touch screen calibrating in order to get it to work.

Since Ubuntu Mate is based on Ubuntu why is it that I have to calibrate. In theory they are the same OS.

regards,
